keeping forms filled in after redirect

I have just finished my form to the way I like it for validation thanks to help from my previous post. But now the problem I have is that when a validation error occurs I send the user back to the registration page with a query in the URL like Name=False only the entire form is cleared and they must start all over again. Is there a way with asp to keep the forms filled in except certain ones like the password and the fields with errors. Thanks for any help.

The form I am working on is http://www.roadhousegossip.com/bdecom/register.asp

Create a global.asa file in the root of your web and dim some session variables in the Session_OnStart subroutine - e.g.

Sub Session_OnStart
    Dim Save_First
    Dim Save_Last
End Sub

In your registration page assign the value of each session variable to its respective form field - e.g.

  <p> First Name: 
    <input name="First" type="text" id="First" value="<%=Session("Save_First")%>">
    Last Name: 
    <input name="Last" type="text" id="Last" value="<%=Session("Save_First")%>">
  </p>

In your form handler (looks like it's form.asp), assign the contents of each form field to its respective session value.

Session("Save_First") = Trim(Request.Form("First"))
Session("Save_Last") = Trim(Request.Form("Last"))
